Abstract

Intracellular 2,7-dichlorofluorescin (H(2)DCF) oxidation is often used to measure the production of reactive oxygen species (ROS) within cells. The rate of H(2)DCF oxidation depends on the concentration of glutathione, which is an alternative target for ROS. Our results suggest that increased rate of H(2)DCF oxidation be interpreted as an indication of general oxidative stress due to a variety of reasons, including depletion of antioxidants, rather than as a specific proof of augmented ROS formation.
